To all @h-0m t may concern.' Y

Beit known that I, JOSEPH GAYNoR, a'

'citizen of the United States, residing at New York city, county and State vof Newy York, have invented a new and Improved p Resilient Vehicle-Wheel, of which the following is a specification.

This invention relates to a resilient vehicle wheel provided with spring-actuated Spokes of novel construction that insure a smooth and easy running of the vehicle, so

that pneumatic tires'may be dispensedwith.

The wheel is further so constructed thatv it contains but a minimum number ofparts and that it may be readily adapted to axles n of different dimensions, so itis unnecessary for the manufacturer tomaintain an unduly large stock of different ywheels to suit the different makesof automobiles and other ve hicles. n.

'In the accompanying drawing: Figure l is a side view of a vehicle wheel embodying my invention, with some of the parts omitted; Fig. 2 an venlarged axialsection, partly broken away, on-line2 2, Fig. 1k; Fig. 3 a longitudinal section partlyy broken away, on line 3 3, Fig.v 2;V Fig. 4 a cross section on line 4 4, Fig. 3, and Fig. 5 a sectional view of a modified form` of the spokes.

The wheel hub is composedofja plateor disk 10 provided with an outer. angular` flangeor shell 11, an octagonal ange being shown correspondingto the eight spokes kA illustrated in Fig. 1.k The free edge of flange v11 is overlapped by the correspondingly y 's shaped rim 12 of a plate or disk 13l arranged opposite plate 10. The parts 10, 13 are provided with opposed octagonal shoulders 14` upon which is seated an angular flange 15 arranged concentricallyto ange, 11 Vvand forming part of a web 16 that is placed flat againstplate 10.` Eachspoke A is composed n 45- of a tubular sleeve 17 rhaving rightk and leftA threaded ends which Lare tapped into the sinner and outer cross heads 18, 19 respectively. If desired, jarnnuts 2O may be prol vided for holding the parts inthe position to which they have been set. Into the inner, end of. sleeve 17 is loosely 'fitted a hollow plunger 21 provided with `a perforated cross` piece 22 which is accommodated betweenv plates 10, 13 andis fulcrume'd thereto by ya screw, bolt 23, resilient washers 24'being preferably interposed between cross piece 22 rests against shell 11, vheads 27 bear against flange 15,the springs28 being always under'y considerable tension. f In like manner, each cross head 19 isreceived ,within a corre# sponding cut-out 30 of the wheel rim'31 which is of U-shapedl cross section as illusthe-heads 27 of which and rplate 25 f trated in Fig. 3. Into the outer end of sleevel `.17 isloosely fitted a hollow T-shaped plunger 32'accommoda-ted between the flanges *i of the rim and fulcrumed thereto by a bolt 33, resilient 'washers 34 being interposed between said plunger andflanges.v Cross head 19 is held. against a curved plate 35 by springs 36 encompassing headed bolts 37, the' parts ^32,l 33, 35, 36, 37 being substantial duplicatesof, the parts 21, 23, 25, 28, 26 above described. `Rim 31 is snugly embraced by la flanged ring 38 that inturnreceives the, preferably `solid tire 39 made kof rubber or other resilient material., f f

`In order to securely hold yring 38 to rim 31, they former is vprovided witha plurality of transverse ribs 40 arranged Ii'n ,radial alinement with spokes A and engaging corresponding notches 41 provided in one of the flanges of-rim 31.` Inassembling the parts,

ring 38 isy slipped over rimv 31 with its'ribs 40 engaging thenotches y41 until said yribs abut againstthe solid rim-flange. A rib-' retaining plate 42 is then interposed between the notched flange4 and the nut 43 of each,`V bolt 33, to securely hold ring 38 with -tire y 39 in position.

In order to prevent from creeping in between ksprings 36, the latter are inclosedby ahousing 44 abutting any dust'of the road f against ring 38 and "notched as at 45 'for l i of this housing extend upwardV against the transverse web. of the U-shaped rim 31, while its side walls'47 are of less height to permit a yfree movement of platey 35. l/Valls 47 are perforated for the reception of boltsl 33 l-whichthus maintainthe housings in posi-r tion. Before assembling the parts, sleeves Athe reception yof 'ribs740. `Theend walls 46y 17 and plungers 21, 32 are filled with grease which, owing to the telescoping movement of said slee-ves and plungers, will insure a thorough lubrication, while the grease may be replenished from time to time through a hole 17a of sleeve 17.

During travel, the sagging of the wheel axlel will cause a telescoping action between the plungers 21, 32 and the sleeves 17 of the bottom spokes, so that all four springs of each spoke are simultaneously compressed. At the same time the four springs of the top spokes are also compressed owing to the lengthening of said spokes, whereby plates 25 will recede from rim 11. Simultaneously with the described shortening and lengthening of the bottom and top spokes respectively, the lateral spokes will be reflected out of their normal radial position. This movementl of the spokes can take place owing to their hinged connection with the hub and wheel rim, and will likewise cause a compression of springs 2S and 86. In this way, all of the spring-influenced spokes are utilized for taking up the shock, so that a smooth and easy running of the vehicle is insured.

In case of light vehicles, the outer springs 36 and cooperating parts may be entirely dispensed with, as illustrated in Fig. 5. In this case,there is secured to the outer end of each sleeve 17, a forked member 4S which is by bolt i9 fulcrumed to the solid rim 31"L of the wheel.

The wheels are held in stock without having provided plates 10, 16 and 18 with central perforations, so that the wheels may be itted to axles of any configuration and diameter. It the proper dimensions of the axles etc. have been ascertained, corresponding bores are provided in parts 10, 16 and 13 to accommodate the central hub sect-ion 50 to which the wheel is secured by bolts A51.

I claim:

In a resilient vehicle wheel, a pair of parallel disks, an inner flange and a concentric apertured outer flange interposed between said disks, a sectional spoke accommodated by the aperture of the outer flange, means for pivoting one spoke member to the disks, a cross head carried by the other spoke member, and a pair of springs interposed between said cross head and the inner flange.

2. In a resilient vehicle wheel, a pair of parallel disks, a pair of concentric polygonal flanges arranged therebetween, the outer ange being provided with a plurality of apertures, sectional spokes accommodated by said apertures, means for pivoting one member of each spoke. to the disks, a cross head carried by the other member' of each spoke, and a pair of springs iiiterpised between eaoh cross head and the inner fl'iange.

3. In a resilient vehicle wheel, a pair, of parallel disks, an inner fiange and a con'- centric apertured outer flange interposednbetween said disks, a sectional spoke accommodated by the aperture of the outer' flange, means for pivoting one spoke member to the disks, a cross head carried by the other spoke member, a plate adapted to engage said cross head and the outer flange, and a pair of springs interposed between said plate and the inner flange.

7. In a vehicle wheel, a rim of U-shaped cross section, a sleeve, a cross head adjustably secured thereto, a plate adapted to engage said cross head and the rim, a T- shaped plunger telescoped by the sleeve and pivoted to the rim, a ring encompassing the rim, means for securely holding the ring to the rim, springs interposed between the plate and the ring, and a tire carried by the ring.
